Review on Portable Car Heater Defroster: Fast Heat, Defrost & Defog with 2-in-1 Function, 3-Outlet Design, Adjustable Thermostat - 12V 150W - Red by Jason Flores

These are pretty good but basic RPi3 cases. The white ones show internal LEDs, which can be an advantage or a problem. The included heatsinks are good, the screws fit well and the shape feels solid. There are multiple vendors for virtually the same chassis, but keep one thing in mind. The case is not big enough (2mm shorter) to connect standard DuPont connectors to the GPIO and still assemble the case. So if you plan to prototype and use GPIO pins and plan to connect them to an external device in the small space available, you will need to modify these headers or use a different method.
